Thermal insulation cotton and benzene board are both commonly used as insulating materials, especially for interior walls and thermal insulation applications. However, their fire resistance properties differ significantly. Benzene board is more affordable and offers good thermal performance, which makes it popular in many insulation projects. On the other hand, thermal insulation cotton not only provides excellent heat and sound insulation but also has superior fire-resistant qualities, making it a safer choice for home use.
Insulation Cotton vs. Benzene Board
When exposed to fire, thermal insulation cotton shows remarkable resistance. In the first few seconds, there's almost no visible change. The area directly under the flame may turn slightly yellow, but it doesn't burn or break down easily. After about 15 seconds, some odor may be released, but the damage remains localized around the flame, with the surface remaining intact.
In contrast, when a flame comes into contact with benzene board, it begins to melt almost immediately. A 2 cm thick piece of benzene board can quickly develop a hole, allowing open flames and dark smoke to escape. It also emits a strong, unpleasant burnt smell. While benzene board is cost-effective and widely used for insulation, its low fire resistance makes it less ideal for residential settings where safety is a priority.
Considering both performance and safety, thermal insulation cotton is often recommended for home use. It offers a balanced combination of insulation, noise reduction, and fire protection, making it a more reliable option for modern homes.
